Re: [soundtrack] Xenojam - Cathedral
Not all of your chord progressions sound intentional... Its kinda atonal on some parts then goes back to more regular types of chords. 2:20 I liked the more sustained notes provided some contrast and increased the mood.
I think it needs more structure and the atonal bits need to sound more deliberate. when you alternate between common chords and atonal, diminished, augmented...etc try to make it less random. Or if chaos is what your truly after try making it more deliberately more chaotic and if you ever go back into a major minor etc.... make that sound more intentional as well.
How you move forward depends if you want to stick to a certain key or if you want to be more abstract.
